Oh, Errrr....... I don't know actually. I think you need to find someone with the repair skill. Or just get as much Alien Epoxy as possible when you go to Mothership Zeta. That stuff will repair ANY weapon you have to maximum (If you use multiple ones) no matter what your repair skill may be...... Defiantly worth having....

Yep! It's awesome stuff! One word of advice though, Anything you really want from Mothership Zeta you should take to your house. DON'T leave it in the containers on the ship as you may not be able to get back there due to a glitch in the game.
